The Lowdown

Alright folks, Rusty here. Let’s take a hard look at what’s on the table for the next couple of weeks. I’ll be straight with you – it’s been a lean stretch and it’s going to stay that way for a while.

We’re looking at a long, dry spell starting right now. The first real hope of anything surfable doesn’t show up until Saturday, August 29th. Before that, from Thursday the 20th right through Friday the 28th, it’s flat or close to it, with weak energy and mostly poor conditions. The swell is tiny, the period is short, and the wind is rarely your friend. There’s a couple of glassy mornings late in that stretch, like Sunday the 23rd, but with swell at only 2 feet and a weak period of 6 seconds, there’s just not enough push to get excited about.

The only session that breaks the silence is Saturday morning, August 29th, at Kennebunk Beach. The water temp is sitting at 66°, which is about 1° warmer than usual for this time of year, so nothing crazy – just a normal, comfortable Maine summer water temp. The winds are calm, glassy, and the combined energy of the swell is 134 (moderate). The swell is 3 feet from the SE with a period of 8 seconds. It’s not a world-beater, but after all that nothing, it’s the one and only standout. The break is sheltered and fairly consistent, but it’s also a beach break, and with that short period, the waves might be a little soft and crumbly. Still, the clean conditions will make it the most fun you’ll have in this forecast window. The rest of that day and the following days drop right back into tiny, weak, onshore junk.

Looking further out, the first few days of September see a slight uptick in energy, with the 3rd of September showing a 4 feet swell from the SE with a period of 8 seconds and some offshore wind from the NE (160 combined energy). It’s a chance, but it’s a full week and a half away so keep your expectations in check. The pattern is for small, clean, but very ordinary waves.

In short, if you’re itching to paddle, your one real window is the morning of Saturday the 29th. It’s not pumping, but it’s clean and it’s all we’ve got.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
